RELATIVE FEEDING VALUE OF SOME GRAIN RATIONS. 
FEEDING EXPERIMENTS WITH Cow NELLIE. 
For a feeding experiment during the winter of 1888-9, the 
Jersey cow Nellie, 6 years old, was selected for the purpose. The 
cow was fresh in milk, having dropped her calf November twenty- 
six. The feeding begun December eleven and continued until 
February twenty-two, the time being divided into four periods as 
follows:

We take the averages for the last ten days of each period so as 
to eliminate the influence due to the changes in food. Linseed 
meal was not relished by the cow, and the amount eaten per day 
was variable. 
The milk yield gradually fell off during the corn meal period, 
Averages for the last ten days of each period— cow Nellie.

but the substitution of an equal weight of gluten meal for corn 
meal caused an increased flow of milk, which was well maintained 
through the period. The substitution of crushed oats for gluten 
meal failed to maintain the quality of milk during the third period, 
and in the fourth period the linseed meal, poorly eaten, maintained 
nearly the same yield as the oats for the whole period, but for the ~
